Most Distant X-Ray Jet Yet Discovered Provides Clues To Big Bang [17 November 2003] - The most distant jet ever observed was discovered in an image of a quasar made by NASA's Chandra X-ray Observatory. Extending more than 100,000 light-years from the supermassive black hole powering the quasar, the jet of high-energy particles provides astronomers with information about the intensity of the cosmic microwave background radiation 12 billion years ago.

Chandra "Hears" A Black Hole [12 September 2003] - NASA's Chandra X-ray Observatory detected sound waves, for the first time, from a super-massive black hole. The "note" is the deepest ever detected from an object in the universe. The tremendous amounts of energy carried by these sound waves may solve a longstanding problem in astrophysics.

Pulsars That Rock Space and Time [02 September 2003] - Envision a bright and beautiful spherical rock, about 10 miles across, packed so tightly and spinning so quickly -- at about 20 percent light speed -- that it actually shakes the fabric of space as if it were a bowl of Jello.

The Hole Story? New Type of Black Hole Poses Challenges [10 April 2003] - A half-century ago, black holes were thought of as little more than
bizarre, hypothetical ideas arising from some of Einstein's equations taken
to their extreme. Today, black holes are accepted by astronomers
as a basic component of the Universe. Under the "standard model" of
black holes, they come in two classes: the stellar and the supermassive.

Eta Carinae, a Home-Grown Mystery [28 January 2003] - Even as astronomers probe the farthest edges of the Universe billions of
light years away to unlock its wondrous mysteries, there are still
baffling mysteries right here in our own Milky Way Galaxy. A big,
beautiful star named Eta Carinae is one such example. At the American
Astronomical Society meeting in January, scientists presented new data
about this enigmatic star that challenges long-held beliefs.
